.WATE R-WHEEL BUCKET.

SPECIFICATION forming part of Letters Patent No. 356,977, dated February 1, 1887.

Application filed November 17, 1886. Seijal No. 219,200. (No model.)

pact of a stream of water issuing from a nozzle under head or pressure against suitablyformed buckets secured to the rim or periphery of the wheel, said-wheels being usuallyknown by the name of hurdy-gurdy.

My invention consists in the devices which I shall hereinafter fully describe and claim.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a perspective view of my bucket.

2o-Fig. 2 is a perspective view showing the bucket applied'to the wheel and the arrangement of the nozzle. Fig. 3 is a cross-section on line X X, Fig. 1.

The bucket A, which is approximately rectangularin shape, has its sides turned to form the flanges at, making the cavity or face of the bucket. In this face a central ridge, a, is formed, wider at the bottom than at the top, and extending upwardly to about two-thirds of the height of the bucket, thus dividing the face or cavity of .said bucket into two depressions, a, into which extend the points or lower ends of the lateral ridgesa which commence at the top edge of the bucket, as shown, and

extend downwardly on each side of the central ridge and parallel, these lateral ridges being wider above than below, and terminating short of the lower end of the bucket. The depressions formed by these three ridges have othe shape approximately of the letter W.

The ridges are all tapering, with gently-curved apices.

In the depressions a, at their lower portion, may be formed concentric corrugations a,

4 5 though these are not essential, and maybe omitted, if found desirable. The'upper edge of the bucket is formed with two spaced parallel flanges or arms, B, between the bases of which is a triangular-shaped portion or lug,

wheel 0, as shown in Fig. 2, the flanges B em- In fitting the bucket to the rim of the.

each bucket successively as it comes into line.

The stream strikes the central ridge, a, near its upper end. It will be observed that in giv ing this central ridge a gently-curved apex I not only obtain a good impact-surface, but

bring this surface as close to the nozzle as pos-' brace the rim, passing on each side thereof, and the triangularly-shaped lug b fits into a tained. It has not as long a distance to pass before striking as it does in order to reach the bottom of the ordinary scoop shaped bucket. The water, striking the slightlycurved apex of the central ridge, divides itself and passes to each side, where, meeting the lat eral ridges a, it drops down, after expending its reactive force against saidridges, and is discharged from the depressions of. The concentric corrugations a in these depressions further assist in utilizing the reaction of the water and providing for its discharge.

Itwill thus be seen that with my bucket I gain the best impact of the stream and the freest discharge, after utilizing to'the greatest extent the reactive force of the water. These hurdy-gurdy wheels.

I am aware of a bucket used in this class of wheels the cavity of which is divided completely into two distinct chambers by means of a central division, the stream striking the apex of this division, which is a sharp one.

I do-not claim the division of the bucket into two chambers, as such is not the object of my central ridge, nor is it its effect. My ridge is but a partial division, and, moreover, is not sharp at its apex, but is gently rounded, thus results are those sought to be attained by all providing for the proper impact-surface at the claim as new, and desire to secure by Letters Patent, is-

1. A water-wheel bucket the cavity or face of which is provided with a central perpeir,

dicnlar ridge extending from the base up wardly part way of the height of the bucket, said ridge being wider at the bottom than at its top, and having its apex tapering and gently curved for receiving the impact of the stream, and lateral tapering ridges extending from the top downwardly part way of the bucket and on each side of the central ridge, substantially as herein described.

2. The water-wheel bucket A, having the side flanges, (I, the central ridge, a, wider at its base than at its top, and extending but part way of the height of the bucket, said ridge having a gently-curving and tapering apex, and

the lateral ridges a, extending downwardly flOIllhhO top of the bucket on each side of the central ridge, wider at the top than at the bottom, and having gently-curving tapering apices, substantially as herein described.
